The Universe at : when and how did the `Dark Age' End?
Martin J. Rees
This paper considers how the first subgalactic structures produced the UV radiation that ionized the intergalactic medium before , and the `feedback' effects of the UV radia…
Dense, thin clouds and reprocessed radiation in the central regions of Active Galactic Nuclei
Z. Kuncic, A. Celotti, M. J. Rees
The primary radiation generated in the central continuum-forming region of Active Galactic Nuclei can be reprocessed by very dense, small-scale clouds that are optically-thin to Th…
Destruction of Molecular Hydrogen During Cosmological Reionization
Zoltan Haiman, Martin Rees, Abraham Loeb
We investigate the ability of primordial gas clouds to retain molecular hydrogen (H_2) during the initial phase of the reionization epoch. We find that before the Stromgren spheres…
Physical constraints on the sizes of dense clouds in the central magnetospheres of Active Galactic Nuclei
Z. Kuncic, E. G. Blackman, M. J. Rees
The range of microphysical and global dynamical timescales in the central regions of Active Galactic Nuclei (AGN) is sufficiently wide to permit the existence of multiphase structu…
21-cm Tomography of the Intergalactic Medium at High Redshift
Piero Madau, Avery Meiksin, Martin J. Rees
We investigate the 21-cm signature that may arise from the intergalactic medium (IGM) prior to the epoch of full reionization (z>5). In scenarios in which the IGM is reionized by d…
How small were the first cosmological objects?
Max Tegmark, Joseph Silk, Martin Rees +3
The minimum mass that a virialized gas cloud must have in order to be able to cool in a Hubble time is computed, using a detailed treatment of the chemistry of molecular hydrogen.…
